It's definitely not a sandbox if you can just "use python to write files" outside of it o_O

Hence the article’s security theatre remark.

I’m not sure why everyone seems to have forgotten about Unix permissions, proper sandboxing, jails, VMs etc when building agents.

Even just running the agent as a different user with minimal permissions and jailed into its home directory would be simple and easy enough.

I'm just guessing, but seems the people who write these agent CLIs haven't found a good heuristic for allowing/disallowing/asking the user about permissions for commands, so instead of trying to sit down and actually figure it out, someone had the bright idea to let the LLM also manage that allowing/disallowing themselves. How that ever made sense, will probably forever be lost on me.

`chroot` is literally the first thing I used when I first installed a local agent, by intuition (later moved on to a container-wrapper), and now I'm reading about people who are giving these agents direct access to reply to their emails and more.

Here's OpenAI's docs page on how they sandbox Codex: https://developers.openai.com/codex/security/

Here's the macOS kernel-enforced sandbox profile that gets applied to processes spawned by the LLM: https://github.com/openai/codex/blob/main/codex-rs/core/src/...

I think skepticism is healthy here, but there's no need to just guess.

If I'm following this it means you need to audit all code that the llm writes though as anything you run from another terminal window will be run as you with full permissions.

That still doesn't seem ideal. Run the LLM itself in a kernel-enforced sandbox, lest it find ways to exploit vulnerabilities in its own code.

		The LLM inference itself doesn't "run code" per se (it's just doing tensor math), and besides, it runs on OpenAI's servers, not your machine.
